摘要：

华北盆地地下热水的水文地球化学分带对水文地质动力分带有着积极的响应特征和很好的指示作用，自周边山区至华北盆地内部，自浅部向深部，地下热水的水质逐渐变差，18O漂移程度越来越大，2H过量参数d值越来越小，指示循环交替条件逐步变差。地下热水高矿化度带的分布特征说明西部、北部的太行山、燕山为华北盆地地下热水的主要补给区，鲁西南山区的补给比例相对较小。水化学的分布特征说明，在盆地平面和垂向上，存在砂岩类地下热水的向心流(渗入成因水)与离心流(沉积成因水)的水动力平衡带，反映了向心流与离心流是此消彼长的动态平衡关系。

Abstract:

The hydrogeochemical zonations of geothermal water in North China Basin can be used to indicate the hydrodynamic zoning because the latter actively responded to the former. The quality of geothermal water is deteriorating and the deuteriumexcess parameter decreases from surrounding mountains to the basin and from shallow to depth in North China Basin, suggesting that the rate of groundwater circulation become slower and slower. The distribution characteristics of high salinity zoning of geothermal water indicate that the Taihang Mountains and Yanshan Mountains in the west and north are predominant recharge area of geothermal water in North China Basin, while a small recharge amount is from the mountains in the southwest of Shandong Province. In addition, whether in the horizontal or vertical direction in the basin, the hydrogeochemical zonations also indicate that there is hydrodynamic equilibrium zone between the centripetal flow (infiltration original water) and acentric flow (sedimentary original water) of geothermal water in sandstone. This indicates that there is transient equilibrium between the centripetal flow and the acentric flow.

Key words: hydrochemical zonation, hydrodynamic zoning, response, geothermal water, North China Basin
